The world’s top central bankers see supply chain problems prolonging inflation.

The joint appearance of some of the world’s most powerful economic officials, sponsored by the European Central Bank, came during a turbulent week in financial markets. While stocks were rebounding on Wednesday morning, they had fallen sharply on Tuesday as government bond yields rose. Investors have been shaken by a political standoff over the debt ceiling in the United States, problems in China’s heavily indebted property sector, the reality that global central banks are preparing to dial back economic support and the possibility that recent rapid price gains might last.

The burst in inflation has swept Europe and the United States this year as consumer demand booms but factory shutdowns and shipping snarls keep many goods in short supply. Central bankers have consistently argued that those price increases will prove temporary. As businesses adjust to the postpandemic recovery, they say, supply-chain kinks will unravel. And while consumers have been spending down savings stockpiled during the pandemic and padded by government stimulus, those will not last forever.

But economic officials have increasingly acknowledged that while they expect the inflationary pop to be temporary, it may last longer than they initially anticipated.

In the United States, consumer price inflation came in at 5.3 percent in August, and the Fed’s preferred inflation gauge — the personal consumption expenditures, or P.C.E., index — grew 4.2 percent in the year through July. August P.C.E. data is slated to be released on Friday.

Consumer prices are expected to peak “slightly above” 4 percent later this year in Britain, double the central bank’s target.

Elsewhere in Europe, inflation is also high, though the jump has not been as large. Euro-area inflation came in at 3 percent in August, the highest reading in roughly a decade. But price gains there are expected to slow more materially over the coming years than in Britain and the United States.

Japan is a notable outlier among developed economies, with slow demand and inflation near zero. Weak inflation leaves central banks with less room to help the economy in times of trouble, and can fuel a cycle of economic stagnation, making it a problem.
